No need to grab both plane and crtc locks at the same time, we can do them one after the other. If userspace races it'll get what it deserves either way. This removes another user of drm_modeset_lock_crtc. There's only one left. v2: Make sure all access to primary->state is properly protected (Harry).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
